The phosphide ion is stable
The Nitride ion - sometimes called an azide.
The phosphide ion, with formula P-3.
The ion of phosphorous (P) is P^3- and is referred to as phosphide.
P3-
P3- This is the phosphide ion, but it is not stable in water, only with 3H in PH3 (comparable with ammonia NH3) or with some metal ions (eg. Li3P, Ca3P2, AlP) it is found as pure substance. There are also other form with negatively charged phosphorous in it.
Nitride Ion.
Phosphide ion is composed of only Phosphorus
Phosphorus ion (PĀ³ā») typically gains three electrons to achieve a stable electron configuration. As a result, it carries a charge of -3 and has a full outer electron shell.
P3- ion (phosphide ion) is formed
Phosphorus will form the phosphide (P3-) ion.
Lead is a metal. It is the 82nd element. It forms the Pb2+ and Pb4+ ions. Azide is a negative ion with the formula N3-. It cannot occur on its own , it needs some positive ion to balance its charge (example the sodium ion Na+ to form sodium azide, NaN3). Compounds with this ion, called azides, are explosive.
Phosphorus forms a -3 ion called phosphide.
